Yes. Way too rushed. It became hard to keep up with it, with it going back and forth in time, and seemingly missing some parts.
I also got a feeling that it was supposed to be the ending...? Just weird all around.
Me too. And on the last page it was written 'fin' (the end).
But I believe the novel is much longer.
yyyeeaaahhhh that just makes me all the more convinced not to finish this manga. It started off so strong too but maybe it was meant to only be read in it's original form i.e. the novel
Manga only ending. This means that this series was done primarily to promote LN sales instead of an actual serious adaption. Or, it could be because of the fact that they are running out of material to draw from based on published materials. Either way, check out the LN translation if you are interested in continuing.
The last chapter was confusing.
